telephone lines, a cable modem can be used to achieve more

bandwidth. Cable network also requires modularization and

demutualization process while sending the data.

Call Center

A call center is a central place where customer and other telephone

calls are handled by an organization, usually with some amount of

computer automation. Typically, a call center has the ability to handle

a considerable volume of calls at the same time, to screen calls and

forward them to someone qualified to handle them, and to log calls.

Call centers are used by mail-order catalog organizations,

telemarketing companies, computer product help desks, and any large

organization that uses the telephone to sell or service products and

services.

Caller ID

A feature that displays the name and/or number of the calling party on

the phone's display when an incoming call is received. For this feature,

the telephone should be equipped with digital reader.

Category 5 cabling

One of the five UTP cable types defined by the EIA/TIA-586 standard

supporting max. 100 Mbits/second (10BASE-Tx) data transmission.

CBR

Constant Bit Rate. A data transmission that can be represented by a

non-varying, or continuous, stream of bits or cell payloads. Applications

such as voice circuits generate CBR traffic patterns. CBR is an ATM

service type in which the ATM network guarantees to meet the

transmitter's bandwidth and Quality of Service requirements

CES

An acronym for Circuit Emulation Service. enables users to multiplex or

to concentrate multiple circuit emulation streams for voice and video

with packet data on a single, high-speed ATM link without a separate

ATM access multiplexer.

Checksum

A computed value which is dependent upon the contents of a packet.

This value is sent along with the packet when it is transmitted. The

receiving system computes a new checksum based upon the received

data and compares this value with the one sent with the packet. If the

two values are the same, the receiver has a high degree of confidence

that the data was received correctly.

Coaxial cable

A cable with a single inner conductor with foam insulation and braided

shield. There are two types of this cable; 50Ω cable for digital signaling

process and 75Ω cable for analog signal process and high speed

digital signal process.

CODEC

An acronym for COder-DECoder 1. Built-in circuit device for

coding/decoding of analog signal to bit stream with Pulse Code

Modulation method. 2. DSP software algorithm for compressing/
